Audrina, pictured just a few hours earlier, and then coming out of one of her dozens of breathing episodes. Her oxygen saturation has dropped into the 50%, and she gets very blue and unresponsive. They don't think its anything serious, but we will be here a few days until they rule everything else out just in case. She just had an ultrasound of her brain to check for a brain bleed. We are waiting for an echocardiogram now.
